In order to maintain corrected nasal tip projection, strong support is important. Authors used calvarial bonegraftmethod for this purpose. Patients were followed up about permanency of the bonegraft for a long time.
None of the patients showed size change or displacement. But the portion of graft facing the tip was absorbed resulting in loss of tip projection and short nose in two patients. One patient had fracture on the middle of the graft. This caused depression from lower portion of the dorsum to the tip.
CONCLUSION:
Despite of autogenous grafts such as calvarial bone, absorption of the bone may occur when compressed with tension for a long period. And the graft in the nasal tip not having any contact with the nasal bone may cause absorption of the graft.
